Stone River at Night, photo by Harold Davis. View this image larger.

This is a night view of the Andy Goldsworthy installation Stone River at the Stanford University campus. I used two exposures, one for the sky and one for Stone River. The blue on the right in the sky is the rising moon.

Exposure data: two captures (one at 30 seconds, one at 85 seconds); both captures 18mm, f/5.6 and ISO 200, tripod mounted.
